for the purpose of utilizing all the surface 'of the disk where the recording is interrupted and needle removed from the disk;

and for repeating any'particular part of a record when the instrument is used for teaching or other purposes.

The manner in which I accomplish my object is described in the following specifications and illustrated in the accompanying drawing in which vFigure 1 is a top view of a box ilu-losing the mechanism; the record disk mounted thereon; the supporting bracket; the horn and reproducer and a scale supportedabove the disk adjacent to the line of travel of the needle. Fig. 2 is a detail showing an adjustable screw pivoted on the center shaft of the mechanism and supporting" one end of the scale. Fig. 3 is a detail view of an adjustable screw pivoted in `the top of the box and adapted to support the other cud of the scale.

In the drawings A indicates the box containing the motor mechanism.

The dotted line B indicates the end of the vertical shaft ou which the record disk C is supported and by which it is rotated.

" insertible in one of the holes F in the ,box A.

By ,the adjustment of these screws the height Llcfthe scale' D above the disk can be regulated. The edges of the scale form part of a circle, the center of which is the pivotal point of the bracket and arm supporting the needle and horn. The face of the scale is divided by marks adapted to indicate any desired point on the disk at which the operator desires to set the needle.

The needle is indicated by the letter G. The reproducer by the letter H. The bracket by I. The arm by the letter J. The pivotal point by Land the horn by K. All of these parts except the scale and its adjustdable screws are referred to simply as usual parts of the instrument of this kind.
